Moore will get a short cameo in the film, which will star Amanda Seyfried as Lovelace and Peter Sarsgaard as her ex-husband and porn production manager Chuck Traynor. It is a bit ironic that she'll play Steinem, as one of her best known roles is that of a stripper in "Striptease." Featuring as Lovelace's co-star in "Deep Throat," the iconic porn film that made Lovelace famous, will be Adam Brody, who is best known for his work on "The OC." Eric Roberts has also been added to the cast as a lie detector expert.

In December, James Franco was reported to be in talks to join the film as Hugh Hefner another celebrity cameo. Hank Azaria in December signed on to play Jerry Damiano, the director of "Deep Throat."

Last seen in the ensemble financial drama "Margin Call" and the Sam Levinson-directed drama "Another Happy Day," Moore will next be seen alongside Miley Cyrus in the comedy "LOL."
